smuX.nvbufferY.clear
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Function Clears the buffer.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage smuX.nvbufferY.clear()
Remarks This function clears all readings from the indicated buffer.
Details See Reading buffers in this section and in Section 7.
Also see smuX.measure.overlappedY, smuX.measure.Y, smuX.nvbufferY
Example Clears SMU A Buffer 1:
smua.nvbuffer1.clear()
smuX.nvbufferY.clearcache
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Function Clears the cache.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage smuX.nvbufferY.clearcache()
Remarks This function clears all readings from the indicated cache.
Details See Reading buffers in this section and in Section 14.
Also see smuX.nvbufferY
Example Clears SMU A reading Buffer 1 cache:
smua.nvbuffer1.clearcache()
smuX.nvbufferY.collectsourcevalues
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Attribute Source value collection for the buffer.
Default 0
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
state = smuX.nvbufferY.collectsourcevalues -- Reads collection state.
smuX.nvbufferY.collectsourcevalues = state -- Writes collection state.
state Source value collection status.
Set state to one of the following values:
0 Source value collection disabled (off).
1 Source value collection enabled (on).
Remarks
• Assigning a state value to this attribute enables or disables the storage of source values.
Reading this attribute returns the state of source value collection.
• When on, source values will be stored with readings in the buffer. This requires four extra bytes
of storage per reading.
• This value, off or on, can only be changed when the buffer is empty. The buffer can be emptied
using the
smuX.nvbufferY.clear function.
Details See Reading buffers in this section and in Section 7.

Example
Include source values with readings for SMU A Buffer 1:
smua.nvbuffer1.collectsourcevalues = 1
